Hi Erik - Thank you! I have not yet looked at nanoVNA firmware and supposed more similarity to SDR than evidently exists. I need to do homework here: * do SA612s not feed I and Q into ADC? * does not

I tried but something is wrong. I would like to try a tool for the original ady555 binary.

Edy555 has implemented in his GitHub nanoVNA repository a command to set the threshold for switching to harmonics mode Command threshold {Frequency in Hz} The default is 300MHz. After changing you can

I like it. I've been using a VM with Ubuntu 18.04, so this gave me a chance to try Windows 10. I'm already a DIYer who uses STM chips, so flashing firmware is pretty comfortable to me. What I am

@Oristo The help file refers to quadrature sampling done with the SI5351 and the two SA612. This is wrong. Some of the references go to IQ downconversion for SDR but the nanoVNA works differently The

I am preparing an updated menu annotated map, based on attached menu screen shots, of which I captured 15. Let me know if I missed any or have suggestions e.g. for improving annotations of unchanged

Herb, Thanks for your comments. You make good points to remember. I am not presently in a position to have a "gold" standard available. That would be nice. And, I am not in need of absolute National

I have tested your nice App with a Moto e5 Android 8 and I see data corruption of S21 that changes in frequency and density from sweep to sweep. Beside that, all seem to work fine! 73, Norbert, DG1KPN

Hi When it comes to the NanoVNA numbers may be somewhat confusing. I for one do have some difficulties sorting one H/W from the other and even more so when it comes to the F/W. I would be surprised if

Very good Mario, better than my needle, will give it back to my wife. Any pencil with only plastic on the tip, and the lead retracted, works. It is still sharper than my needle. Torbjorn

bryburns, I think its always a good idea to keep in mind that the NanoVNA is a mass produced product intended for the hobbyist market. If your requirements need a certain level of confidence then your

Excellent idea! Roy WA0YMH wrote:

I found an old Sakura "Nocksos NS100c" disposable drafting pencil laying around here that has a hard all plastic tip when the lead is retracted. It works absolutely perfectly for a stylus on this

The easiest way to imagine it is to place a 3dB attenuator on the CH0 port and measure the Return Loss with nothing connected to the other side of the attenuator so that is open circuit. The power

Return loss is a measure of the loss of incident power that is not being returned because it is being "lost" to the load resistance.

Folks, I am interested in learning how much I can trust the results from my nanoVNA. I understand that a T-Check is a good approach to evaluate VNA performance. Here are the results of a brief
